I'm working with the MVC .NET and I used the WebSecurity layer in order to manage logins and roles.
What happens if I have several users with the same "username" in my db and I call the following funciton?
Roles.GetRolesForUser(username)
Is it possible to say to my dbo.User table that I want that the pair "username+column2" must be unique? If yes, how can I retrieve the roles for that pair?
